User blog comment:SquidSpooks/Why is Morrison black in DMC5 but white in the anime?/@comment-37885014-20181225191051

They're just using the character from the anime (which isn't confirmed to be canon) and retool him into the main continuity. SO the white version is basically non-canon. So for the black version, even though he has a similar personality to the white version, may get a different backstory.
